DIRECT GAS-FIRED SUSPENDED UNIT HEATER 



features a horizontal, tubular heat exchanger. This all-welded, steel exchanger has no gaskeled, slip or tie-rod 
joints. Heat is evenly distributed over the exchanger, with no flame impingement on the outside walls. The 
horizontal, tubular design provides maximum scrubbing of air over the heat-transmitting surfaces, with uniform air 
temperatures over the entire discharge area. The unit is fired by a drilled-port, cast iron burner, with no cross- 
lighting problems. The Type 150 can be serviced from the bottom without lowering. It is shipped assembled and 
pre-wired. A.G.A. approved and listed by Underwriters' Laboratories, Inc.

GAS-FIRED BOILERS 

are versatile, attractive, compact units designed and built to comply with the requirements or the ASME code. 
All are readily adaptable to hot water heating, gravity or forced circulation, steam or vapor heating, radiant 
heating, or hot water supply. The Types 10 and 11 are designed primarily for residential installation, while 
the Type 20 is used extensively for commercial and industrial applications. The Type 10 boiler is finished in 
gleaming white baked enamel or green crinklfe finish. The Type 11 is the same as the Type 10, except the con- 
trols are exposed and it is finished in green only. These Mueller Climatrot boilers are of sectional cast iron 
construction. They are equipped with cast iron drilled-port burners.

COIL UNIT AND CONDENSING UNITS 

the Type 900 Summer Air Conditioning Unit is universal in application since it can be in- 
corporated in any forced air heating system having sufficient blower capacity. The compact 
coil housing is installed in the duct system at the time of the original heating installation or 
at a later date, as desired. 

The Condensing Unit shown below is for use with either Type 900 or Type 901 Summer Air 
Conditioning Units. It is a compact unit of semi-hermetic design.

pouches are integral parts of the combustion chamber with complete circulation of air around them, providing 
additional heating surface. The pouches extend through the one-piece steel shield, with the fire and ashpit doors 
hinged directly to them. The square-cased Type 702 is a winter air conditioner, with built-in blower compart- 
ment which can be installed on either side.

REGISTERS AND GRILLES 

complete stock for all requirements on conventional, perimeter and Muelleraire systems. 
Line also includes automatic thermostatically controlled registers. 



LEVELIZER CONTROL SYSTEM 

maintains room temperature at a constant comfort level regardless of outside temperature. It consists 
of a Levelizer Regulator and Duct Controller. The Levelizer is used instead of the conventional gas 
pressure regulator and the controller is installed in the return air compartment. The Levelizer operates 
with a standard type thermostat, which acts as a top temperature limiting device, and provides con- 
tinuous heat delivery by regulation of the gas flame itself. As room temperature decreases, more gas is 
supplied to the burner, which increases the size of the flame and provides more heat to the home. As 
room temperature increases, the quantity of gas furnished the burner decreases, which lowers the flame 
and reduces the amount of heat furnished the home. Since the Levelizer Control 5ystem operates almost 
constantly, it provides uniform, floor-to-ceiling temperatures and prevents stratification.
